Wyoming Dinosaur Center, Paleontology museum in East Thermopolis, United States

The Wyoming Dinosaur Center is a private fossil museum in East Thermopolis, Wyoming, with a gallery of more than 50 mounted skeletons. Its centrepiece is a 106-foot replica mount of Supersaurus vivianae, built from data on the second and most complete Supersaurus found, nicknamed "Jimbo" and donated in 2003. Displays also cover marine and flying reptiles, Devonian fish and invertebrates, and fossil camels, horses and nimravids, and a working preparation lab is visible to visitors.

The museum was founded following the discovery of dinosaur bones at Warm Springs Ranch in 1993, which sparked the creation of this research facility. Ongoing excavations in the area have continued to yield fossils that are now displayed and studied here.

The center's preparation lab is open to view all year, where staff and visitors clean, repair and preserve fossils from Warm Springs Ranch and other sites. Summer programs include Dig for the Day for families and individuals, a Kids' Dig for ages 8 to 12 covering digging, matrix removal and molding, plus Dinosaur Academy and Senior Activities. All fossils found stay at the museum for research.

The museum offers visitors the chance to participate in hands-on dig programs at nearby sites, learning how to identify fossils and record findings properly. These activities let you experience the actual work that paleontologists do in the field.

The Archaeopteryx on display is the Thermopolis Specimen, which the center acquired in 2005 from a private donor who had held it for several decades. It is one of only two real specimens of the genus shown outside Europe.
